He learns that an ongoing war between the Sevateem and the Tesh was instigated by Xoanon, the god they both worship. In reality, an all-powerful computer, Xoanon, is possessed by a desperate madness directly related to the Doctor - one which only the Time Lord can rectify! In order to do battle with Xoanon, the Doctor must escape, not only from the savage practices of the Sevateem but also from the mind-controlling impulses of the Tesh.

When the power source begins to fluctuate, the whole planet is threatened. Zastor, Tigella's leader, welcomes the Doctor and invites him to arbitrate; yet the Time Lord may not be all he seems.
